Hi, I'm trying to build a standalone app for a virtual cohort generator, to be deployed on a machine without matlab installed. Matlab version R2022b, glnxa64 architecture, fedora 36. The build fails with the following message (after echoeing the command line that leads to the error):
Error while determining required deployable files. Compilation terminated. Details:
fl:filesystem:SystemError
...
mcc failed.
When I run the echoed mcc command from a terminal, the verbosity is slightly better:
mcc -o virtual_cohort_generator_gui -W main:virtual_cohort_generator_gui -T link:exe -d /home/marcelr/edu/PhD/sabine/virtual_cohort_generator_gui/virtual_cohort_generator_gui/for_testing -v /home/marcelr/edu/PhD/sabine/virtual_cohort_generator_gui/virtual_cohort_generator_gui.m
mclCopyDir failed: Failed copying '/home/marcelr/.matlab/R2022b/matlab.prf' to '/tmp/mcc1d83-aada-fcda-6d43.tmp/user/matlab.prf': reason 'fl:filesystem:SystemError'
Failed to copy user-level MATLAB settings from "/home/marcelr/.matlab/R2022b" into temporary directory "/tmp/mcc1d83-aada-fcda-6d43.tmp/user". Cannot continue without risk of corrupting MATLAB settings.
What could be the problem here? File permissions are set to full access (for the user (me)).

I had the same problem. For me, the solution was to set TMPDIR to point somewhere but not to /tmp/
